On the system with the IPMP group configuration, assume the Primary Administrator role or become superuser.
The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
Add the interface to the IPMP group.
# ifconfig interface group group-name
The interface specified in interface becomes a member of IPMP group group-name.
To add hme0 to the IPMP group testgroup2, you would type the following command:
# ifconfig hme0 group testgroup2 hme0: flags=9000843<UP ,BROADCAST,RUNNING,MULTICAST,IPv4,NOFAILOVER> mtu 1500 index 2 inet 192.168.85.19 netmask ff000000 broadcast 10.255.255.255 groupname testgroup2 ether 8:0:20:c1:8b:c3
